Circuit Schematic 20 Watt Integrated Amplifier using TDA2005

Amplifier. - This is electronic circuit schematic of 20 Watt Integrated Amplifier using TDA2005 like in Figure 1 below. In this circuit schematic the basic component used is TDA2005. 

In here we will give you global description about 20 Watt Integrated Amplifier using TDA2005 and then we will give you link to continue your reading from original source as external website.

Circuit Schematic

Component Part

  • TDA2005 IC
  • Transistors

  • Capacitor
  • Variable resistor
Description

Circuit schematic like in Figure 1 above is Circuit Schematic 20 Watt Integrated Amplifier using TDA2005. Eleccircuits site describe that the heart of this project following as figure circuits, at number IC1 TDA2005 (and TDA2004 are used interchangeably). That is IC use for the stereo amplifier, inside comprise of two op-amp that both is connected with the bridge model for power increate up. And it can use to DC power supply 12 volt. And importance it is able to response frequency from 35 Hz to 15 KHz.

When we know IC1 (TDA2005) is sufficient, following the principles of the overall circuits. Start a input signal will be into this circuit through the capacitor C1 Before, this signal is amplified by transistor Q1. Which capacitors C2,C3,C6 and potentiometer VR2 adjusts the signal level or the high frequency sound.


The capacitor C4,C5 and potentiometer VR3 is defined a Level of the low frequency or bass sound. The signals through VR1 to adjust the size of the signal to be sent enlarge, with be coupling through capacitor C8 to the input pin 1 of IC1, to Enlarge next sign.
